Hi, In practice it is the equivalent, since the ffiCall has a return type and it takes precedence over the ^ of Pharo. Personally, I often add the ^ to ffiCalls that have a return to easy the reading, but the output will be the same. Esteban On May 10 2021, at 2:12 pm, Tomaž Turk <tomaz.turk@ef.uni-lj.si> wrote:
Dear all,
Should the method that calls Object>>#ffiCall: and variants always return the result of this call? For instance, in uFFI book, there is a method abs: defined as
FFITutorial class >> abs: n [ ^ self ffiCall: #( int abs (int n) ) ]
on page 16, however
FFITutorial >> abs: n [ self ffiCall: #( int abs (int n) ) ]
on page 52 doesn't have an explicit return ^. The book, however, in most of the examples uses the explicit return. What is the recommended approach?
Thanks, Tomaz
